Detailed Description

Caller-owned I2C target context.

This is a public value type, not an opaque handle. Applications may allocate it statically, on the stack, or as part of another structure. Initialize it with mcp2221_i2c_slave_init() before using any other slave helper.

The context borrows the underlying mcp2221_t handle; destroying or overwriting the context does not close the MCP2221 device.
